Silence "TZID without Luxon available is unsupported" logs

Reporting an issue

Love the package but v2.6.6 has introduced a lot of noise in our logs. I've also gone ahead and added Luxon as a dependency but am still receiving the warning.

We're using fromString which has a tzid already in it.

Thank you for taking an interest in rrule! Please include the following in
your report:

• Verify that you've looked through existing issues for duplicates before
  creating a new one
• Code sample reproducing the issue. Be sure to include all input values you
  are using such as the exact RRule string and dates.
• Expected output
• Actual output
• The version of rrule you are using
• Your operating system
• Your local timezone (run $ date from the command line
  of the machine showing the bug)

Just ran into this. Using date-fns instead of Luxon and would rather use date-fns to handle conversions.

Since the maintainers are absence I created a "patch" to silence it.

function SILENCE_CONSOLE_ERROR_PATCH() {
    const origError = console.error;

    console.error = function () {
      const message = arguments[0];

      if (message !== 'Using TZID without Luxon available is unsupported. Returned times are in UTC, not the requested time zone') {
        origError.apply(this, arguments);
      }
    }
  }

I understand that the error is there to make sure the user avoids unintentional behavior, but the example in the README seems to allow it without the results referencing Luxon.

https://github.com/jakubroztocil/rrule/tree/286422ddff0700f1beb2e65cebff3421cc698aac#important-use-utc-dates

const rule = RRule.fromString(
  "DTSTART;TZID=America/Denver:20181101T190000;\n"
  + "RRULE:FREQ=WEEKLY;BYDAY=MO,WE,TH;INTERVAL=1;COUNT=3"
)
rule.all()

...

// You can get the local components by using the getUTC* methods eg:
date.getUTCDate() // --> 1
date.getUTCHours() // --> 18

Need to add a static flag or some other configuration to RRule to allow silencing it manually, or the library needs a better way of providing a date conversion.
